Question 1

Polyatomic ions

Answer 1

lons that are formed when a group of atoms gains or loses electrons.

Question 2

Nonpolar covalent bond

Answer 2

A covalent bond in which the electrons are shared equally between the atoms involved.

Question 3

Polar bond

Answer 3

A covalent bond in which the electrons are shared unequally between the atoms involved.

Question 4

Nonpolar molecule

Answer 4

A covalent molecule in which the electrons are evenly distributed throughout the whole molecule.

Question 5

Polar molecule

Answer 5

A covalent molecule that has an imbalance in the distribution of electrons throughout the whole molecule.

Question 6

Polar covalent compounds can dissolve

Answer 6

other polar covalent compounds and ionic compounds because both types of compounds contain electrical charges.

Question 7

Nonpolar covalent compounds can dissolve

Answer 7

only other nonpolar covalent compounds because no electrical charges are present.
